Porous nitrogen-doped graphene ribbons for future electronics

Nearly 200 billion naïve T cells continuously patrol the human body in a dormant state, prepared to respond to potential threats.

Organisms exposed to challenging environments face evolutionary pressure to adapt, which could lead to modifications in a variety of traits, such as morphology, physiology and behaviour.

Global water consumption has increased almost fourfold in the past 100 years, and many regions can only meet their water demand thanks to essential contributions from mountain regions. In 30 years, almost a quarter of the world's lowland population will strongly depend on runoff from the mountains. Only sustainable development can ensure the important function of mountain areas as Earth's "water towers".

Frailty and immune decline are two main features of old age. Researchers from the University of Bern and the University Hospital Bern now demonstrate in an animal model that these two age-related impairments can be halted and even partially reversed using a novel cell-based therapeutic approach.
